Frequently asked questions
What is an H-frame electrical stamping used for?
H-frame electrical stampings form the stator laminations of three-phase induction motors typically 1–10 HP. The H-shape provides a balanced magnetic flux path for the three phases.
How is H-frame different from E-frame?
E-frame stampings are for single-phase and small motors; H-frame stampings are optimised for three-phase induction motors with balanced coil geometry. See our full E-frame vs H-frame guide.
Can you supply H-frame stampings in different stack heights?
Yes — we cut to any customer-specified stack height. Common heights: 40–180 mm. Larger stacks on request.
What is the lead time?
For existing tooling: 5–10 days. New tool: 3–4 weeks. Faridabad NCR delivery same-day/next-day.
